JavaScript - Change A Select Box Value With Javascript?
Here's the code that I'm working with:
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script type ="text/javascript"> function HouseSel(){ document.getElementById("HouseSelect").value = '3' alert (document.getElementById("HouseSelect").value); } </script> </head> <body> <form action="https://www.paypal.com/us/cgi-bin/webscr" method="post" name="_xclick"> <select name="item_name" id="HouseSelect"> <option value="0" selected="selected">--Please Select a House--</option> <option value="1">Nags Head</option> <option value="Rent Deposite: Calib ">Calibre</option> </select> <input name="calculate3" type="button" id="calculate3" tabindex="2" onclick="HouseSel(); " value="Calculate"/> </form> </body> </html> But it's still returning the initial value. How do I get it to 3? Similar TutorialsI've been having problems getting my select option to change the options of another select option. I'm not much of a javacsript coder, so I'm at a lost. When I select the first option nothing appears in the second option. here's the javascript code: Code: function createOption(OptionText, OptionValue){ var temp = document.captcha_form("option"); temp.innerHTML = OptionText; temp.value = OptionValue; return temp; } function valChange(){ var firstList = document.getElementById("emailaddress"); var secondList = document.getElementById("subject"); while(secondList.hasChildNodes()) secondList.removeChild(secondList.childNodes[0]); switch(firstList.value){ case "1":{ secondList.appendChild(createOption("Report Site Browsing Issue", Report Site Browsing Issues)); secondList.appendChild(createOption("Report Page Errors", Report Page Errors)); secondList.appendChild(createOption("Other", Other)); break; } case "2":{ secondList.appendChild(createOption("Report Unauthorized Game", Report Unauthorized Game)); secondList.appendChild(createOption("Report Spam", Report Spam)); secondList.appendChild(createOption("Report Harassment", Report Harassment)); secondList.appendChild(createOption("Report Illegal Activities", Report Illegal Activities)); secondList.appendChild(createOption("Request Account Removal", Request Account Removal)); break; } // .... default:{ secondList.appendChild(createOption("Please select from the first list", "")); break; } } } window.onload = valChange; this is the form code Code: <div class="mailto_form"> <form method="POST" id="captcha_form" name="captcha_form" action="../includes/mailform.php"> <div style="padding-bottom: 1em;">Choose Recipient: <select name="emailaddress" id="emailaddress" onchange="valChange();"> <option value=""></option> <option value="1">Webmaster</option> <option value="2">Admin</option> </select> </div> <div style="padding-bottom: 1em;">Subject: <br /><select name="subject" id="subject"> </div> <div style="padding-bottom: 1em;">From: <br /><input type="text" name="email" id="email" value=""> </div> <div style="padding-bottom: 1em;">Enter the text contained in the image into the text box: <br /><img src="../includes/captcha.php" /> <br /><input type="text" name="userpass" value=""> </div> <div style="padding-bottom: 1em;">Message: <br /><textarea name="message" id="message" rows="10" cols="60"><?php echo "</tex" .

The student is supposed to select one main course as well as provide a second choice in case the first is not available. I have two dropdown select fields to capture data 1) Choice -1: 101 / 102 / 103 ( Student needs to select one - Reading the classID from classes table) 2) Choice -2: 101 / 102 / 103 ( If student selects 101 in Choice-1 then the only classes available under Choice-2 should be 102 or 103). How can I accomplish the above? Further to this there are two fields on the form where I would like to auto populate based on what they have selected in Choice-1 and Choice-2. For Example: If a parent selects choice1: 101 the child Choice1 field should autopopulate with 100. If a parent selects Choice2: 201 the child Choice2 field should autopopulate with 200 Any help would be really appreciated. Thanks Vinny I have html like this Code: <form> <select name="otype[]" class="txtText" id="otype[]"> <option value="Processing">Processing</option> <option value="Shipped">Shipped</option> </select> some code...... <select name="otype[]" class="txtText" id="otype[]"> <option value="Processing">Processing</option> <option value="Shipped">Shipped</option> </select> some code....... <select name="otype[]" class="txtText" id="otype[]"> <option value="Processing">Processing</option> <option value="Shipped">Shipped</option> </select> I need to change all select lists options to "Shipped" if admin clicks on "Shipped" on top of the page and "Processing" if customer clicks on "Processing" link (<a href="javascript:select_processing()">Processing</a>) Can somebody help me in doing so? I am trying to change a character limit based on items changed in a drop down menu. To do this I have one function that will change the posted count based on the currently selected option and another function that is a commonly used char count with a few tweaks. The main issue is getting the value of the currently selected option. I know that selectedIndex will return the position of the selected element rather than the actual value. I tried to code around that. I've tried every method I could find on google and nothing works. So, I may have a bigger problem on a higher level that I just don't understand. If any of you can take a look at my code and give me your thoughts I would be most appreciative. Thanks!

A friend gave me the code below, but I can't get it to work. Thanks so much for your help Code: <script type="text/javascript"> $('#Gift_Type').change(function(){ if ($(this).val() == 'Monthly'){ $('#name').val('Partnership') $('#category').val('Partnership') } else { $('#name').val('Donation') $('#category').val('Donations') } }) </script> Code: <SELECT NAME="sub_frequency" ID="Gift_Type" onchange="OnSelectionChanged (this)"> <OPTION VALUE="1m">Monthly</OPTION> <OPTION VALUE="">One Time</OPTION> </SELECT> Code: <input type="text" id="name" name="name" value="Partnership" /> <input type="text" id="category" name="category" value="Partnership" /> Hello all, I am having a problem, and since I am quite new in the Javascript code I hope somebody can help me here. This is my current code: Code: <select class="Form" name="opties"> <option value="AAA">AAA</option> <option value="BBB">BBB</option> <option value="SLX" selected>Selecteer optie</option> </select> Now my intention is the following: When the option with value SLX gets selected it needs to get a special css style. It is not a problem to give the option this style in the list itself, but once selected it always changes to the original style (standard font and color) in Chrome and Mozilla. Now I searched on the net and sometimes I find things like this: Code: function displayOption(divName) { document.getElementById(divName).innerText=document.form1.select1.options[document.form1.select1.selectedIndex].value; } <select class="Form" name="opties" onChange="displayOption('div1');"> <option value="AAA">AAA</option> <option value="BBB">BBB</option> <option value="SLX" selected>Selecteer optie</option> </select> But I suppose this always changes the style of the selected item? It only needs to change when the option SLX is chosen... Anyone knows how to solve this problem? the script below should open a new window with a url specified in the select area. However, my script ignores the changes in the select area. it keeps opening the same page. I was wondering could someone take a look and tell me why?

I'm hoping someone could help me out or point me in the right direction. I am trying to set up a simple interaction for users. The user would be required to select a width then height from two separate drop down menus. I used this as an example to work from: http://www.w3.org/TR/WCAG20-TECHS/wo...dynselect.html The list of heights would not be available until the user selects a width.(similar to the example link above). Each width would have slightly different heights associated with it. After the user selects a width then height an image would be displayed based on that combination. So for example if the user selects 12w/30h they would see "01.jpg" if the user selects 12w/36h they would see "02.jpg". This would all be done on the same page. The user should be able to update the image by combining the different width/height options indefinitely. If anyone has a link to an example or can provide a basic structure I could build of off I would be extremely grateful, thanks. I have two drop down lists , list1, list 2. I want it to change according to the radio button selected by the user. If the user selects radio button1, lists1 should be displayed. If the user selects radio button2, lists2 should be displayed. How can i achieve this using javascript. Please somebody help me. all i have to do is the image to change automatically based on the option you selected from the drop down list. here is the code, any help is appreciable. thanks in advance. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <style type="text/css"> img{ height:95px; width:95px; display:block; margin-top:10px; } #caption{ font-family:Verdana,tahoma,arial; font-size:8pt; text-align:left; display:block; width:250px; } </style> <script type="text/javascript"> window.onload=function() { var caption=['Default Image Caption', 'begonia', 'daffodils', 'mixture', 'natural', 'purple', 'red flower', 'sunflower', 'tulip', 'two flowers'], // This will be your images caption bp='..\images', //base url of your images imgnum=9, //Number of your images.

Many thanks in advance Glorifindal Ok so I'm making this form which when a selection is made in one box it will run through the javascript(function getMgmtHours), and update the div(mgmthours). Then another box shows up allowing another selection to be made which runs through the javascript(function getDays) and updates another div(mgmtdate). My problem is that when I use the second box to run through javascript, it overwrites what shows up in the first div (mgmthours) when it should be updating a different div (mgmtdate). Any ideas what I can do to get it update the relevant div and not overwrite the other one? Here is part of the javascript I have in my page head: Code: function getMgmtHours(str) { if (str=="") { document.getElementById("mgmthours").innerHTML=""; return; } if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("mgmthours").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","getmgmthours.php?dist="+str,true); xmlhttp.send(); } function getDays(str) { if (str=="") { document.getElementById("mgmtdate").innerHTML=""; return; } if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("mgmtdate").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","getdates.php?sunday="+str,true); xmlhttp.send(); } Here is the HTML/PHP portion being used: PHP Code: echo "<p>"; echo "Submit hours:"; echo "<form>"; echo "<select name='district' onchange='getMgmtHours(this.value)'>"; echo "<option value=''>Select a district:</option> <option value='1'>1</option> <option value='3'>3</option> <option value='4'>4</option>"; echo "</select>"; echo "</form>"; echo "</p>" echo "<p>"; echo "<form action='./hours.php' method='post' onSubmit='return checkMgmtHours'>"; echo "Weekending Day: "; echo "<select name='weekending' onchange='getDays(this.value)'>"; echo "<option value=''>Choose a Date:</option>"; while ($week < 32) { $nextsunday = strtotime("next Sunday"); if ($week > 0) { $timestamp = strtotime("-" . $week . " week", $nextsunday); } else { $timestamp = $nextsunday;} $weekending = date('M. d, Y', $timestamp); echo "<option value='" . $weekending . "'>" . $weekending . "</option>"; $week = $week + 1; } echo "</select>"; echo "<div id='mgmtdate' />"; echo "<div id='mgmthours' />"; echo "</p>"; Edit: Also, after getMgmtHours() runs, I can still use both getDays and getMgmtHours, howeer once I used getDays, I am no longer able to use getMgmtHours w/o refreshing the page. Hi, what would be the best way to have a hidden array of possible text directed at a textarea and then if something is not within that array "onfocus", a certain select option is chosen within that form? Thanks Hi all, I am a newbie to JS. So please extend your help suggesstion to solve this problem I have. I have 2 select boxes. Data in one select box is corresponding to the data in the other select box. When the user comes in and selects example the 3rd element from the first or second select box the correspoinding 3rd element from the other select box should be selected. Please help with the solution.Thanks in advance I have got this piece of code where JavaScript will change a FORM OPTION if it has been selected before (incase the user returns to the page - doesn't have to refill in things), but its not working and my web browser reports this error: Quote: Error: document.getElementById("Dr") is null This is the code: Code: <SCRIPT type="text/javascript"> document.getElementById("<?php echo $_SESSION['recipient']['title']; ?>").selected = "selected"; </SCRIPT> Code: <FORM action="process.html" method="post"> <DIV class="deliveryinformationdata"> <DIV> <B>Title:</B> <SELECT name="title"> <OPTION></OPTION> <OPTION id="Dr">Dr</OPTION> <OPTION id="Miss">Miss</OPTION> <OPTION id="Mr">Mr</OPTION> <OPTION id="Mrs">Mrs</OPTION> <OPTION id="Ms">Ms</OPTION> </SELECT> </DIV> <INPUT type="submit" value="Submit"> </DIV> </FORM> Can anyone see a problem? Hi, would someone know how to convert the left side (textbox) into the same thing as the right has (select box) also by modifying the JS code from the example of this URL: http://www.mredkj.com/tutorials/tableaddrow.html ? It would be a really good feature to have if two select options were used from side-to-side rather than a textbox and a select list. Hi Guys, I am posting this to see if anyone has any ideas or sample code that has worked in the past. What i am aiming at doing is having two tables, with the same amount of rows side by side, effectively rendering them the same. I wish then to select a row on the one table, and this event would trigger the same row on the 2nd table to be selected too. Has anyone done something like this before? Appreciate any feedback! Thanks. Hey, how do I make the following accessible if JS is disabled? Code: <select onchange="if (this.selectedIndex > 0) location.href=this[this.selectedIndex].value;"> <option value="www.domain.com">Your Domain</option> </select> Hello guys, I am working with javascript and currently have the below code set up. This works well, however I would like to change the "select box" to a "search box"- When the user enters a search string, the matching DIV appears.
